Day 50 of Insanity

My posts are getting lame b/c there isn't anything much new to report. Max Interval Plyometrics kicked my butt like usual. I'm still not able to get through the entire workout without having to stop and catch my breath. Lately I've been noticing that I'm just wore out from all these workouts. I wonder if I'm over-training or what. I've got less than 2 weeks to go and then I'm taking a break for no more than a week before I start the hybrid workouts. I need a rest b/c I feel run down and my heart isn't in it like it should be.
